Methods and systems for creating and using a location identification grid

ABSTRACT

A method and system for generating a location identification grid and for using a location identification grid. The location identification grid can include a first geographic area that correspond to a pre-existing area. This pre-existing area can correspond to a postal code such as a zip code, a telephone code such as, an area code, or any other desired pre-existing area. The location identification grid can be subdivided into smaller geographic areas to allow more accurate identification of a location. The location identification grid can include a second geographic area. The second geographic area can be a subdivision of the first geographic area. The location identification grid can be used with signals that identify a location within a location identification grid. These signals can include a first component corresponding to the first geographic area and the second component corresponding to one or more second geographic areas.

Description of the Related Art

Location identification is done in a number of ways including, forexample, relative location, addressing, and through the use of gridsystems.

Determining relative location is a long used method of developinglocation identification. Relative location is with reference tolandmarks or other identifying features. While relative location issimple, it is difficult to reliably use, as landmarks may be difficultto consistently identify. Relative location is also difficult to usebecause the landmarks and other identifying features can change overtime. Thus, while relative location is useful in facilitating locationidentification, it also has drawbacks.

Addressing is another method of location identification. Addressing canbe performed by, for example, identifying a street and a location on thestreet. In many instances of addressing, the location on the street isassociated with buildings or properties located on the street. Whileaddressing provides a more reliable form of location identification, italso has several difficulties. Addressing can be a very inefficient formof location identification for a person who is unfamiliar with an areaor with a street. For example, a person may not be able to find thestreet referenced in an address. Further, addressing isn't intuitive, inthat the name and location of one street is usually not indicative ofthe name or location of another street. Thus, a person must be familiarwith the area in which the address is located in order to know how touse addressing to find a location. Further, as addressing relies onrelative positioning on a street, and as the relative position isusually defined relative to property or structures, changes in property,changes to the structures on the street, and/or changes in the streetitself can make the addressing system difficult to use. Anothershortcoming of addressing is that an addressing system does notaccurately identify locations within properties or other locations notassociated with the property.

The association of a grid-type system with the land area is anothermethod of location identification. Such systems include, for example,latitude and longitude on the globe, and the national grid system. Whilegrid systems allow accurate identification of a location, and while theidentification of the location is independent of physical landmarks orphysical identifying features, a grid system also has shortcomings. Oneof the greatest shortcomings of a grid system is that it is separatedfrom daily experience. Thus, a person using a grid system does notusually experience locations in terms of the grid system, but rather interms of addresses and relative locations. Thus, complete reliance on agrid system can cause problems for a new user. Further, grid systemsfrequently identify a point and do not identify an area.

In light of these shortcomings, a new method and system of locationidentification is required to facilitate intuitive and accurate locationidentification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Some embodiments described herein relate to systems and methods forgenerating a location identification grid. Some embodiments relatespecifically to methods of creation of the location identification grid.Some embodiments relate to methods for using the location identificationgrid. Some embodiments relate to new techniques and methods foridentifying a location within a location identification grid. Someembodiments relate to hardware and software components that can be usedin connection with the location identification grid.

In some embodiments, a geographic region can be divided into a number ofsmaller geographic areas. In some embodiments, each of these geographicareas can be further divided until a desired level of resolution withinthe grid is achieved. In some embodiments, a location can be identifiedby identifying one or several areas containing the location. In someembodiments, the division of these geographic areas can be divided byapplying an existing grid system such as, for example, a regular grid, aCartesian grid, rectilinear grid, a curvilinear grid, and/or polar gridsystem to these geographic areas. In some embodiments, this grid systemcan include, for example, the national grid.

The location identification grid can be used to identify locationswithin a geographic region. The geographic region can be divided into aplurality of first geographic areas. In some embodiments, these firstgeographic areas can cover the entirety of the geographic region. Thesegeographic areas can be, for example, regularly shaped or irregularlyshaped. In some embodiments, these first geographic areas can be thesame size, can have different sizes, or can fall within a consistentrange of sizes. In some embodiments, these first geographic areas can,for example, correspond to preexisting divisions of the geographicregion.

In some embodiments of the location identification grid, each of thefirst geographic areas can be divided into a plurality of secondgeographic areas. In some embodiments, the division of the firstgeographic areas into a plurality of second geographic areas can be doneby applying a pre-existing grid such as, for example, a regular grid, aCartesian grid, rectilinear grid, a curvilinear grid, and/or polar gridsystem, to the first geographic areas, and in some embodiments, thedivision of the first geographic areas into a plurality of secondgeographic areas can be done by creating a new grid system within thefirst geographic areas.

In some embodiments, the plurality of second geographic areas can coverthe entirety of the first geographic areas. In some embodiments, forexample, the first geographic areas can be divided into secondgeographic areas of a first size. Thus, in this embodiment, the secondgeographic areas of a first size have the same size. In someembodiments, the second geographic areas of a first size can also havethe same shape. However, and in light of the fact that the firstgeographic areas can be irregularly shaped, and can have differentsizes, the plurality of first geographic areas may have differentnumbers of second geographic areas of a first size within the boundariesof each of the first geographic areas, and the second geographic areasof a first size can be different sizes and shapes.

In some embodiments, each of the second geographic areas of a first sizecan be further divided into second geographic areas of a second size. Insome embodiments, the division of the second geographic areas of a firstsize into a plurality of second geographic areas of a second size can bedone by applying a pre-existing grid such as, for example, a regulargrid, a Cartesian grid, rectilinear grid, a curvilinear grid, and/orpolar grid to the first geographic areas, and in some embodiments, thedivision of the second geographic areas of a first size into a pluralityof second geographic areas of a second size can be done by creating anew grid system within the second geographic areas of a first size. Insome embodiments, for example, the second geographic areas of a secondsize can cover the entirety of each of the second geographic areas of afirst size. In some embodiments, the second geographic areas of a secondsize can have the same shape and/or the same size.

In some embodiments, each of the second geographic areas of the secondsize can be further divided into smaller groups, similar to the divisionof the second geographic areas of the first size. This division can beachieved by using similar steps and methods to those outlined above.This process can be continued for each new second geographic area untila desired level of resolution and accuracy has been achieved.

By dividing the geographic region into a number of first geographicareas, a location can be identified based on its existence within theboundaries of one of the first geographic areas. Similarly, by dividingeach of the first geographic areas into a plurality of second geographicareas of a first size, a location can be identified by reference to itslocation within the boundaries of a first geographic area and to itslocation within the boundaries of a second geographic area of a firstsize. The identification of a location can be continuously morespecifically indicated by identifying a location based on its existencewithin the boundaries of progressively smaller second geographic areas.Location identification by identifying continuously smaller geographicareas containing the desired location within the boundaries can beperformed until the desired level of accuracy in the locationidentification has been achieved.

A variety of systems and modules can be used in connection with thelocation identification grid. Similarly, a variety of systems andmodules can be used in connection with the process for identifying alocation by reference to a location identification grid. In someembodiments, for example, a system for use in connection with a locationidentification grid or for use in generating a location identificationgrid can comprise a variety of components and/or modules. Thesecomponents and/or modules can be, for example, hardware or software. Insome embodiments, these modules can be independent devices or can befunctioning within a single device. In some embodiments, these modulesand/or components can communicate with each other. These modules caninclude, for example, a processor, memory, a communications module, asecurity module, and an administrator's module.

In some embodiments, modules of a system for use with a locationidentification grid or for use in generating a location identificationgrid can communicate with a user. In some embodiments, these modules cancommunicate with a user via an interface, or via a user device. In someembodiments, for example, these modules can receive inputs from a user.In some embodiments, these modules can provide outputs and/or prompts toa user.

A person of skill in the art will recognize that a variety ofcomponents, devices, modules, and/or other features can be used in thecreation of a system for generation of a location identification grid orfor use in connection with the location identification grid, and thatthe present disclosure is not limited to any specific system or to anyspecific modules, components, and/or any other features.

A location identification grid can be generated in a variety of ways. Inone embodiment of generating a location identification grid, ageographic region can be identified. This geographic region can bedivided into a series of progressively smaller geographic areas.Specifically, this geographic region can be divided into firstgeographic areas, which first geographic areas cover the entirety of thegeographic region. Each of these first geographic areas can be dividedinto a plurality of second geographic areas of a first size. Similarly,the second geographic areas of a first size can be divided into secondgeographic areas of a second size, which second geographic areas of asecond size can likewise be subdivided into smaller second geographicareas. This process of division of the continually smaller secondgeographic areas can be performed until the desired accuracy andresolution of the location identification grid is achieved. As discussedabove, this division can be achieved by applying a pre-existing systemto the first geographic areas, such as, for example, the national grid.

In some embodiments, smaller “child” geographic areas can be createdfrom larger “parent” geographic areas. In some embodiments, the secondgeographic areas can be created by dividing the parent area in whichthey are located with a plurality of parallel first lines. These firstlines can, in some embodiments, extend from one side of the parentgeographic area to another side of a parent geographic area. In someembodiments, the parent geographic area can be further divided. In someembodiments, these second lines can extend from one side of the parentgeographic area to the other side of the parent geographic area. In someembodiments, the second lines can be, for example, perpendicular to thefirst lines. The creation of second, child geographic areas by aplurality of parallel first lines and a plurality of parallel secondlines, which parallel second lines are perpendicular to the parallelfirst lines, can result in the creation of a number of rectangularlyshaped second geographic areas.

In some embodiments, information relating to the first geographic areasand/or the second geographic areas can be stored in a database.

In some embodiments, a location identification grid can be used in avariety of ways to assist in the identification of a location and toassist in the performance of a variety of tasks. In some embodiments inwhich a location identification grid is used to facilitate theidentification of a location, a signal can be received from a user. Insome embodiments, this signal can include a request for theidentification of a location. In some embodiments, this request caninclude a text stream. This text stream can be divided into components,which components identify the relevant first geographic area and anyrelevant second geographic area or areas. In some embodiments, thesecomponents can be used to determine a location. After the location hasbeen identified and/or determined, information relating to the locationcan be provided to the user.

A person of skill in the art will recognize that the locationidentification grid can be used in the performance of a variety oftasks, and that the present application is not limited to the details ofthe above-disclosed method of using a location identification grid.

Location Identification Grid

FIG. 1 depicts one embodiment of a location identification grid 100. Asseen in FIG. 1 , the location identification grid 100 covers ageographic region 102. The geographic region 102 can comprise a varietyof sizes and shapes, and can have any desired size and shape and caninclude any desired geographic features, such as, for example, cities,mountains, plains, rivers, valleys, or any other geographic feature. Thegeographic region 102 can have a variety of boundaries. In someembodiments, the geographic region 102 can have preexisting boundaries,such as boundaries formed by a coastline, a river line, or any othernatural or manmade or preexisting feature. In some embodiments, thegeographic region 102 can have political boundaries that can include,for example, state boundaries, country boundaries, city boundaries,county boundaries, or any other politically determined boundary. In someembodiments, the geographic region can be a continent such as NorthAmerica, a country such as the United States, or a state such asVirginia.

The geographic region 102 can comprise a plurality of first geographicareas 104. As seen in FIG. 1 , each of the geographic areas 104 caninclude a portion of the geographic region 102. Further, the sum of theplurality of first geographic areas 104 can, for example, encompass theentire area of the geographic region 102. Thus, the entire area of thegeographic region 102 can be, as depicted in FIG. 1 included in thefirst geographic areas 104.

The first geographic areas 104 can comprise a variety of shapes andsizes. In some embodiments, the first geographic areas 104 can comprisethe same shapes and sizes. In some embodiments, the first geographicareas 104 can comprise different sizes and/or different shapes.

In some embodiments, a first geographic area 104 can comprise a regulargeometric shape such as, for example, a circle, a triangle, a rectangle,a quadrilateral, a polygon, a hexagon, a pentagon, or any other desiredregular geometric shape. In some embodiments, the first geographic area104 can comprise an irregular shape. In some embodiments, the firstgeographic areas 104 can comprise a variety of sizes.

In some embodiments, the first geographic areas 104 can comprise, forexample, a group of preexisting areas. These areas can be related topostal systems such as, for example, areas associated with a zip code,related to telecommunications systems such as, for example, areasassociated with an area code, related to political divisions such as,for example, state, county, city, country, or other political region orboundary, or can be related to any other service or purpose. In someembodiments, the first geographic areas 104 can be created solely tofunction within the location identification grid 100.

Each of the first geographic areas 104 can be defined by firstboundaries 106. These first boundaries 106 can, for example, coincidewith a portion of one or more of the boundaries of the geographic region102, or can be independent of the boundaries of the geographic region102. In some embodiments, these boundaries 106 correspond to naturalboundaries, political boundaries, or any other boundaries. Thus, in someembodiments, the boundaries 106 correspond to preexisting dividingfeatures including, for example, rivers, shores, streets, highways,state boundaries, county boundaries, national boundaries, cityboundaries, or any other boundary.

As further seen in FIG. 1 , the first geographic areas 104 can besubdivided into a plurality of second geographic areas of a first size108. The second geographic areas of a first size 108 can comprise avariety of shapes and sizes. In some embodiments, the second geographicareas of a first size 108 can comprise the same shape and size. In someembodiments, the second geographic areas of a first size 108 cancomprise different shapes and sizes. In some embodiments, the secondgeographic areas of a first size 108 can be regularly shaped orirregularly shaped. As depicted in FIG. 1 , in some embodiments, thesecond geographic areas of a first size 108 can comprise a plurality ofrectangles of the same size, or a plurality of squares of the same size.In some embodiments, the second geographic areas of a first size 108 cancomprise a range of sizes.

In some embodiments, and as seen in FIG. 1 , the entirety of the area ofsome or all of the first geographic areas 104 can be covered by secondgeographic areas of a first size 108. Thus, and as seen in FIG. 1 , eachportion of the first geographic area 104 can be included in one of aplurality of second geographic areas of a first size 108.

To provide different levels of accuracy in location identification, afirst geographic area 104 can be divided into any number of secondgeographic areas of a first size 108. In some embodiments, the firstgeographic area 104 can be divided into second geographic areas of afirst size 108 by one or several first boundary lines 110, and one orseveral second boundary lines 112. In some embodiments, these boundarylines 110, 112 can correspond to a pre-existing grid system, such as,for example, the boundaries of the national grid.

In some embodiments, the first boundary lines 110 can be linear ornonlinear. Similarly, in some embodiments, the second boundary lines 112can be linear or nonlinear. In some embodiments, the first boundarylines 110 and the second boundary lines 112 can coincide with thepreexisting boundaries or natural boundaries such as, for example,boundaries defined by a river, mountains, shoreline, a politicalboundary such as a state, a county, a city, or a national boundary, orany other manmade or natural boundary.

In some embodiments, the first boundary lines 110 can comprise aplurality of parallel linear boundaries. In some embodiments, the secondboundary lines 112 can likewise comprise a plurality of parallel linearboundary lines. In some embodiments, the second boundary lines 112 canbe perpendicular to the first boundary lines 110. In some embodiments,the first boundary lines 110 and the second boundary lines 112 candefine a grid.

The number of first boundary lines 110 and second boundary lines 112 canbe the same in each of the first geographic areas 104. In someembodiments, the number of first boundary lines 110 and the number ofsecond boundary lines 112 can vary between first geographic areas 104.In some embodiments, the spacing between the first boundary lines 110and between the second boundary lines 112 can be constant inside asingle first geographic area and between first geographic areas 104.Thus, in some embodiments in which the spacing between the firstboundary lines 110 and the second boundary lines 112 is constant betweenfirst geographic areas 104, the second geographic areas of a first size108 defined by first and second boundary lines 110 and 112, can be, inpart, the same size. In some embodiments, in which the first geographicarea 104 is irregularly shaped, second geographic areas of a first size108 having a boundary that coincides with the first boundaries 106 maynot have the same shape as other second geographic areas of a first size108, or cover the same area as other second geographic areas of a firstsize 108.

As the geographic region 102 is subdivided into first geographic areas104, and as the first geographic areas 104 are subdivided into secondgeographic areas of a first size 108, the specification of a firstgeographic area 104 identifies a portion of the geographic region 102and thereby more accurately identifies a location than merelyidentifying the geographic region 102. Similarly, the specification of asecond geographic area of a first size 108 within a first geographicarea 104 identifies a portion of the first geographic area 104 andthereby more accurately identifies a location than merely identifyingthe first geographic area 104.

FIG. 2 shows a close-up of one of the second geographic areas 108depicted in FIG. 1 . As seen in FIG. 2 , the second geographic area of afirst size 108 is defined by a plurality of boundaries. Specifically,the second geographic area of a first size 108 is defined by a leftfirst boundary line 110 a, a right first boundary line 110 b, a topsecond boundary line 112 a, and a bottom second boundary line 112 b. Asdiscussed above, and as shown in FIG. 2 , the first boundary lines 110 aand 110 b can be parallel. Similarly, and as discussed above, the secondboundary lines 112 a and 112 b can be parallel, and can be perpendicularto the first boundary lines 110 a, 110 b. Due to the orientation of thefirst boundary lines 110 a, 110 b and the second boundary lines 112 a,112 b, the intersection of the first boundary lines 110 a, 110 b and thesecond boundary lines 112 a, 112 b defines a rectangular, and asdepicted in FIG. 2 , a square second geographic area of a first size108. As seen in FIG. 2 , the second geographic area of a first size 108can be further subdivided into second geographic areas of a second size200. In some embodiments, these second geographic areas of a second size200 can correspond to areas defined by a pre-existing grid system, suchas, for example, the boundaries of the national grid.

The second geographic areas of a second size 200 can comprise a varietyof shapes and sizes. In some embodiments, the second geographic areas ofa second size 200 can be the same shape and size. In some embodiments,the second geographic areas of a second size 200 can be different shapesand sizes. In some embodiments, the second geographic areas of a secondsize 200 can be regularly shaped or irregularly shaped.

In some embodiments, the second geographic areas of a second size 200can have any desired area that is smaller than the area of the secondgeographic areas of a first size 108.

In some embodiments, the sum of the plurality of the second geographicareas of a second size 200 can include all of the area of the secondgeographic area of a first size 108. Thus, in some embodiments, eachportion of the second geographic area of a first size 108 is included ina portion of one of the second geographic areas of a second size 200.

In some embodiments, the second geographic area of a first size 108 canbe subdivided into second geographic areas of a second size 200 by oneor several third boundary lines 202 and one or several fourth boundarylines 204. In some embodiments, these boundary lines 202, 204 cancorrespond to a pre-existing grid system, such as, for example, theboundaries of the national grid. In some embodiments, the third boundarylines 202 can comprise one or several parallel boundary lines. In someembodiments, these boundary lines can be linear or nonlinear. Similarly,in some embodiments, the fourth boundary lines 204 can comprise one orseveral parallel lines. In some embodiments, the fourth boundary lines204 can be linear or nonlinear. In some embodiments, both the thirdboundary lines 202 and the fourth boundary lines 204 can correlate topreexisting boundaries, or can be created for the purpose of subdividingthe second geographic area of the first size 108.

The boundary lines 202, 204 can be regularly spaced or irregularlyspaced. In some embodiments, the third boundary lines 202 areperpendicular to the fourth boundary lines 204. In some embodiments, inwhich the third boundary lines 202 are parallel, and are perpendicularto the fourth boundary lines 204, the combination of the third boundarylines 202 and the fourth boundary lines 204 defines a grid.

The division of the second geographic area of a first size 108 into aplurality of second geographic areas of a second size 200 allows a moreaccurate identification of a location, as the existence of secondgeographic areas of a second size 200 within the second geographic areaof a first size 108 allows the specification of a portion of the secondgeographic area of a first size 108 including a specific location.

While FIGS. 1 and 2 only depict dividing a geographic region 102 into afirst geographic area 104, and dividing the first geographic area 104into a second geographic area of a first size 108, which secondgeographic area of a first size 108 is subdivided into a secondgeographic area of a second size 200, a person of skill in the art willrecognize that the second geographic area of a second size 200 can befurther subdivided into smaller second geographic areas of a third size,which second geographic areas of a third size can likewise be subdividedinto smaller second geographic areas of a fourth size, which subdivisioncan continue until a desired level of accuracy within the locationidentification grid 100 has been achieved.

Text Strings Identifying a Location

In some embodiments, the geographic areas of a geographic region 102 canbe uniquely identified. In some embodiments, for example, each of thefirst geographic areas 104 can be assigned a unique identifier, such as,for example, a unique text string. In some embodiments, this unique textstring can comprise a unique identifying number.

In some embodiments, a second geographic area can be uniquely identifiedby identifying the first geographic area containing the secondgeographic area and identifying the second geographic area relative tothe first geographic area.

By way of example, and referring to FIG. 1 , the first geographic area104 containing location 150, unique first geographic area 104 a, can beassigned a unique identifier. As shown in FIG. 1 , the geographic region102 includes seven first geographic areas 104, including unique firstgeographic area 104 a. In one embodiment, each of these seven firstgeographic areas 104 could be uniquely identified by assignment of aunique number. In one embodiment, each of these seven first geographicareas can be assigned a number between one and seven, and unique firstgeographic area 104 a can be assigned, for example, the number one.

Further, the second geographic area of a first size 108 containinglocation 150, unique second geographic area of a first size 108 a, canbe identified. In some embodiments, this identification can be achievedby assigning a unique identifier to each of the second geographic areasof a first size 108. In some embodiments, this unique identifier caninclude information identifying the first geographic area 104 thatincludes the second geographic area of a first size 108, and thatidentifies one of the second geographic area of a first size 108 locatedwith the first geographic area 104. In the embodiment depicted in FIG. 1, in which the first geographic area 104 can be divided into eightcolumns of second geographic areas of a first size 108 and six rows ofsecond geographic areas of a first size 108, a second geographic area ofa first size 108 can be identified within the unique first geographicarea 104 a by identifying its column and row location.

Thus, the unique second geographic area of a first size 108 a, which islocated in the fifth column from the leftmost boundary of the uniquefirst geographic area 104 a, and in the third row from the bottommostboundary of the unique first geographic area 104 a, can be identifiedwithin the unique first geographic area 104 a with “53,” whichcorresponds to the location in the fifth column and the third row. Thus,the unique second geographic area of a first size 108 a can be uniquelyidentified by reference to its location within unique first geographicarea 104 a and its row column location within the unique firstgeographic area 104 a. This identification can be, for example, “153.”

As shown in FIG. 2 , in some embodiments, the location 150 can befurther identified by specifying a unique second geographic area of asecond size 200 a containing the location 150. Like the secondgeographic area of a first size 108, the location of the unique secondgeographic area of a second size 200 a can be uniquely identified byidentifying the unique first geographic area 104 a containing thelocation 150, by identifying the unique second geographic area of afirst size 108 a containing the location 150 relative to the uniquefirst geographic area 104 a, and by identifying the unique secondgeographic area of a second size 200 a containing the location 150relative to the unique second geographic area of a first size 108 a. Inthe embodiment depicted in FIG. 2 , in which the second geographic areaof a first size 108 found in unique first geographic area 104 a can bedivided into seven columns and eight rows, a second geographic area of asecond size 200 can be identified within the unique second geographicarea of a first size 108 a by identifying its column and row location.

Thus, the unique second geographic area of a second size 200 a, which islocated in the fourth column from the leftmost boundary of the uniquesecond geographic area of a first size 108 a, and in the fifth row fromthe bottommost boundary of the unique second geographic area of a firstsize 108 a, can be identified within the unique second geographic areaof a first size 108 a with “45,” which corresponds to the location inthe fourth column and the fifth row. Thus, the unique second geographicarea of a second size 200 a can be uniquely identified by reference tothe unique first geographic area 104 a containing the unique secondgeographic area of a second size 200 a, by reference to the uniquesecond geographic area of a first size 108 a containing the uniquesecond geographic area of a second size 200 a, and by reference to itsrow/column location within the unique second geographic area of a firstsize 108 a. This identification can be, for example, “15345.”

FIGS. 3A through 3C identify a plurality of text strings that can beused to indicate portions of a location identification grid 100corresponding to a location. Referring now to FIG. 3A, FIG. 3A depicts afirst text string 302. A text string can comprise a collection of text.As depicted in FIG. 3A, the first text string 302 comprises a pluralityof first characters 304. These first characters 304 can comprise aletter, a number, or any other symbol.

In some embodiments, the first characters 304 within the first textstring 302 can correspond to, or identify, the position of a locationwithin the location identification grid 100.

In some embodiments, the first text string 302 can be used to identify alocation. In some embodiments, the first text string 302 can include adesired number of first characters 304 to provide a desired resolutionand/or accuracy level in identifying a location. In some embodiments,one or several of the first characters 304 of the first text string 302can be associated with a first geographic area 104 and with one orseveral second geographic areas. In some embodiments, one or several ofthe first characters 304 of the first text string 302 can be associatedwith an entity, a person, a property, an address, and/or any otherdesired item. In some embodiments, the item, including, for example, theentity and/or person, associated with some of the first characters 304of the first text string 302 can be associated with the locationidentified by the remaining portions of the first text string 302. Thus,a first portion of the first characters 304 of the first text string 302can identify a location, and a second portion of the first characters304 of the first text string 302 can be associated with, for example, anentity, a person, a property, or an address. Advantageously, this canfacilitate, delivery of an item to a person at a location by allowingthe identification of the recipient by reference to the text stringand/or information associated with the text string.

In some embodiments, in which the first text string 302 is associatedwith an item such as, for example, a property, an entity, and/or aperson, the first text string 302 can be used as an address, as atelephone number, as an email address, or for any other desired purpose.Advantageously, in some embodiments, the first text string 302 can beconverted into a signal, a computer readable code, and/or any otherdesired format to facilitate its use.

Referring to location 150, location 150 can be identified with the firsttext string 302 of first characters 304 by “153,” as discussed above.This text string identifies a unique first geographic area 104containing the location 150, and the portion of the unique firstgeographic area 104, namely the unique second geographic area of a firstsize 108 a, containing the location.

In some embodiments in which further accuracy is desired, the portion ofthe second geographic area of a first size 108 a containing the location150, namely, the unique second geographic area of a second size 200 a,can be identified. Thus, in some embodiments, information may berequested relating to the location of something covering a large area orinformation may be requested relating to the location of somethingcovering a small area. In the case in which information relating to thelocation of something covering a large area is requested, a lesserdegree of accuracy is required in identifying the location that in thecase in which information relating to the location of something coveringa small area is requested.

In some embodiments, the first text string 302 providing this level ofaccuracy can comprise, for example, “15345.” Similarly, additional firstcharacters 304 can be added to the first text string 302 to provideadditional accuracy to the identification of location 150.

FIG. 3B depicts another embodiment of a text string. Specifically, FIG.3B depicts a second text string 306. As discussed above, the second textstring 306 can have any desired length, and can comprise any desirednumber of text characters. As depicted in FIG. 3B, the second textstring 306 can comprise one or several first characters 304 locatedwithin a first string portion 308, and one or several second characters310 located in the second string portion 312. Like the first characters304, the second characters 310 can comprise a letter, a number, or anyother symbol.

In some embodiments, the first string portion 308 can correspond to andidentify a first geographic area 104. In some embodiments, the secondstring portion 312 can identify and correspond to one or several secondgeographic areas located within the identified first geographic area104.

In some embodiments, in which the second geographic areas are created byone or several first boundary lines that are parallel, and one orseveral second parallel boundary lines, and in which the first boundarylines and the second boundary lines are perpendicular to each other, thesecond string portion 312 can be divided into character pairs.Specifically referring to FIG. 3B, the second string portion 312includes the character pair 310 a and 310 b. In some embodiments inwhich the second geographic areas are created by intersecting andperpendicular first boundary lines and second boundary lines, thecharacter pair 310 a and 310 b can designate a second geographic areasimilar to coordinate pair. Specifically, a first portion of thecharacter pair 310 a can identify a portion of the first geographic area104 divided by the first boundary lines and the second portion of thecharacter pair 310 b can identify a portion of the geographic areadivided by second boundary lines. Thus, by specifying both the firstportion 310 a and the second portion 310 b, a portion of the largergeographic area can be specified.

In some embodiments of the second text string 306 in which the secondstring portion 312 includes more than two second characters 310, theseadditional characters can further specify portions of a largergeographic area. Thus, the first pair 310 a and 310 b may specify theportion of the first geographic area in which the location is found.Similarly, the next pair of identifiers 310 c and 310 d can identify theportion of the first geographic area defined by 310 a and 310 b in whichthe location is found. Likewise, the pair including 310 e and 310 f candefine the portion of the geographic area defined by 310 c and 310 d inwhich the location is found. Thus, by extending the second stringportion to include more character pairs, a location can be increasinglymore accurately identified.

In some embodiments, the second text string 306 can be used to identifya location. In some embodiments, the second text string 306 can includea desired number of first characters 304 and/or second characters 310 toprovide a desired resolution and/or accuracy level in identifying alocation. Similar to the first text string 302, in some embodiments, oneor several of the first characters 304 and/or second characters 310 ofthe second text string 306 can be associated with an entity, a person, aproperty, and address, and/or any other desired item.

In some embodiments, in which the second text string 306 is associatedwith an item such as, for example, a property, an entity, and/or aperson, the second text string 306 can be used as an address, as atelephone number, as an email address, or for any other desired purpose.Advantageously, in some embodiments, the second text string 306 can beconverted into a signal, a computer readable code, and/or any otherdesired format to facilitate its use.

FIG. 3C identifies a third text string 314. Like the second text string306 identified in FIG. 3B, the third text string 314 includes a firstcharacter 304 in a first string portion 308 and a second character 310in the second string portion 312. As depicted in FIG. 3C, the third textstring 314 additionally includes a third character 316 in a third stringportion 318. In some embodiments, for example, the third character 316found in the third string portion 318 can comprise a characterindicating a division between the first string portion 308 and thesecond string portion 312. Thus, in some embodiments, third characters316 found in the third string portion 318 do not identify a location,but assist in separating the first string portion 308 from the secondstring portion 312.

In some embodiments, the third text string 314 can be used to identify alocation. In some embodiments, the third text string 314 can include adesired number of first characters 304 and/or second characters 310 toprovide a desired resolution and/or accuracy level in identifying alocation. Similar to the first text string 302, in some embodiments, oneor several of the first characters 304 and/or second characters 310 ofthe third text string 314 can be associated with, for example, anentity, a person, a property, an address, and/or any other desiredthing. In some embodiments, the thing, including, for example, theentity and/or person, associated with some of the first characters 304and/or the second characters 310 of the third text string 314 can beassociated with the location identified by the remaining portions of thethird text string 314.

In some embodiments, in which the third text string 314 is associatedwith a thing such as, for example, a property, an entity, and/or aperson, the third text string 314 can be used as an address, as atelephone number, as an email address, or for any other desired purpose.Advantageously, in some embodiments, the third text string 314 can beconverted into a signal, a computer readable code, and/or any otherdesired format to facilitate its use.

Referring again to location 150, location 150 can be identified with thethird text string 314 of first characters 304, second characters 310,and third characters 316 by “1 ##53.” In this embodiments the “1” cancorrespond to the first characters 304, “53” can correspond to thesecond characters 310, and the “##” can correspond to the thirdcharacters 316. This text string identifies a unique first geographicarea 104 containing the location 150, and the portion of the uniquefirst geographic area 104, namely the unique second geographic area of afirst size 108 a, which contains the location.

In some embodiments in which further accuracy is desired, the portion ofthe second geographic area of a first size 108 a containing the location150, namely, the unique second geographic area of a second size 200 a,can be identified. In some embodiments, the third text string 314providing this level of accuracy can comprise, for example, “1 ##5345.”In this embodiments, the “1” can correspond to the first characters 304,“5345” can correspond to the second characters 310, and the “##” cancorrespond to the third characters 316. Similarly, additional firstcharacters 304 can be added to the first text string 302 to provideadditional accuracy to the identification of location 150.

A person of skill in the art will recognize that a variety of formatscan be used to identify a location within a location identification grid100. A person of skill in the art will further recognize that thepresent disclosure is not limited to any specific format of informationidentifying a location within a location identification grid 100.

In some embodiments, for example, the identifiedregion can comprise a geographic region 102. In some embodiments, thecentral processing system 402 can identify the region by querying adatabase with location information and determining the regioncorresponding to the location.

After the region has been identified in block 502, the process 500 thenproceeds to block 504 where the region is divided into areas. In someembodiments, the region can be divided into, for example, one or severalfirst geographic areas 104, or one or several second geographic areas.In some embodiments, for example, the central processing system 402and/or the processor 408 can divide the region into areas. In someembodiments, the division of the region into areas can correspond to thecreation of areas making up the region. In some embodiments, thedivision of the region into areas can correspond to the identificationof pre-existing areas that divide up the region. In some embodiments,the pre-existing areas can be already established areas that divide theregion. In some embodiments in which pre-existing areas are used todivide up the region, the suitability of the pre-existing areas can bedetermined before dividing the region up into the areas. In someembodiments, the suitability of the pre-existing regions can bedetermined by determining whether the pre-existing regions fall withincertain criteria such as, for example, size criteria, shape criteria, orany other desired criteria.

In some embodiments, a pre-existing area may be associated and/oridentified with a pre-existing identifier. Thus, for example, an areadefined by a postal code such as a zip-code can be a pre-existing area,and the postal code such as the zip-code is the pre-existing identifierfor the area defined by the postal code such as the zip-code.

After the region is divided into areas in block 504, the process 500moves to block 506 where the areas are divided into a plurality ofsubareas. In some embodiments, for example, the division of areas into aplurality of subareas can correspond to the division of one or severalfirst geographic areas 104 into second geographic areas. In somespecific embodiments, the division of areas into a plurality of subareascan correspond to dividing one or several first geographic areas 104into a plurality of second geographic areas of a first size 108. In someembodiments, for example, the division of areas into a plurality ofsubareas can be performed by the central processing system 402.

In some embodiments, the division of one or several first geographicareas 104 can be achieved by the application of a pre-existing gridsystem to the first geographic areas 104, such as, for example, thenational grid.

After the areas are divided into a plurality of subareas, the process500 moves to block 508 and location information is output. In someembodiments, the location information can be output to a user. Forexample, in some embodiments, the location information can be outputfrom the grid system to a user device 404. In some embodiments, thisoutput can include the communication between the central processingsystem 402 and the user device 404 via the communication system andnetwork 406. In some embodiments, information can be output from thecentral processing system 402 to the communication system and network406 via a communications module 418 of the central processing system402.

A person of skill in the art will recognize that the process 500 caninclude more or fewer steps than those outlined above. A person of skillin the art will further recognize than the above-outlined steps ofprocess 500 can be performed in any desired order, and can includesubsteps or subprocesses.

FIGS. 5A and 5B depict one embodiment of subprocesses performed in block506 of FIG. 5 . In particular, FIG. 5A depicts one embodiment of aprocess 520 for dividing areas into a plurality of sub-areas asindicated in block 506 of FIG. 5 . In some embodiments, the process 520can be performed by the central processing system 402. Thus, in someembodiments in which information relating to a preexisting locationidentification grid 100 is being accessed, the process 520 can includequerying the memory 410 for information relating to the preexistinglocation identification grid 100.

Having this information from block 504 of FIG. 5 , the process 520 movesto block 522 and the area is divided with one or more first parallellines. In some embodiments, this division is performed by the centralprocessing system 402 and/or components of the central processing system402. In such an embodiment, the processor 408 can be configured to querythe memory 410 for information relating to the generation of firstparallel lines. In some embodiments, this information can include, forexample, the spacing between the first parallel lines, the number offirst parallel, including, for example, a maximum and/or minimum numberof first parallel lines, and or any other desired information. Thesefirst parallel lines are then generated and used to divide the area.

Some embodiments can include a wide range of first parallel lines. Insome embodiments, the number of first parallel lines can be determinedbased on the desired size of the resulting areas created by the firstparallel lines. In some embodiments, a single first parallel line may beused to divide the area. In some embodiments, for example, a pluralityof first parallel lines can be used to divide the area. In someembodiments, for example, the number of first parallel lines used todivide the area can be 100, 50, 25, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, orany other or intermediate number of first parallel lines. In someembodiments, for example, the use of a number of first parallel linesless than 10 can allow the use of a single second character 310 toindicate a specific divided subarea of the area. Advantageously, theability to specify a certain divided subarea of the area with a singlesecond character 310 can facilitate the construction of the text stringfor use in identifying a location.

A person of skill in the art will recognize that a wide range oftechniques can be used to divide the area with one or more firstparallel lines and for generating the one or more first parallel lines,and that the present disclosure is not limited to any specificembodiments thereof.

After the area is divided with one or more first parallel lines in block522, the process 520 moves to block 524 wherein the area is divided withone or more second parallel lines. In some embodiments, this division isperformed by the central processing system 402. In such an embodiment,the processor 408 can be configured to query the memory 410 and inputinformation for parameters with which to generate the second parallellines. In some embodiments, this information can include, for example,the spacing between the second parallel lines, the number of secondparallel, including, for example, a maximum and/or minimum number ofsecond parallel lines, and or any other desired information. Thesesecond parallel lines can then be generated and used to divide the area.As discussed above, in some embodiments, the first and second parallellines can correspond to pre-existing lines, such as those associatedwith, for example, the national grid.

Some embodiments can include a wide range of numbers of second parallellines. In some embodiments, the number of second parallel lines can bedetermined based on the desired size of the resulting areas created bythe second parallel lines. In some embodiments, a single second parallelline may be used to divide the area. In some embodiments, for example, aplurality of second parallel lines can be used to divide the area. Insome embodiments, for example, the number of second parallel lines usedto divide the area can be 100, 50, 25, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, orany other or intermediate number of second parallel lines. In someembodiments, for example, the use of a number of second parallel linesless than 10 can allow the use of a single second character 310 toindicate a specific divided subarea of the area. Advantageously, theability to specify a certain divided subarea of the area with a singlesecond character 310 can facilitate the construction of the text stringfor use in identifying a location.

A person of skill in the art will recognize that a wide range oftechniques can be used to divide the area with one or more secondparallel lines and for generating the one or more second parallel lines,and that the present disclosure is not limited to any specificembodiments thereof.

After the area is divided with one or more second parallel lines, theprocess 520 moves to block 526 and defines a sub-area using portions ofthe first and second parallel lines as boundaries. In some embodiments,this definition is performed by the central processing system 402. Insuch an embodiment, the processor 408 can be configured to query thememory and input information for parameters with which to define thesub-area or sub-areas.

The sub-areas can be bounded by portions of the first and secondparallel lines. Specifically, in embodiments in which the first parallellines are non-parallel with the second parallel lines, the intersectionof the first parallel lines with the second parallel lines defines oneor several subareas. In some embodiments, these subareas can comprise avariety of shapes, and in some embodiments in which the second parallellines are perpendicular to the first parallel lines, the subareas cancomprise a rectangular shape.

A person of skill in the art will recognize that the spacing between thefirst parallel lines and the second parallel lines, as well as the anglebetween the first parallel lines and the second parallel lines willdetermine the size and shape of the subareas created by the intersectingfirst parallel lines and second parallel lines.

After one or more subareas are defined by portions of the first andsecond parallel lines, the process 520 moves to decision state 528 wherecomponents of the central processing system 402 determine whetherfurther subdivision is required. In some embodiments, the determinationof whether further subdivision is require is based on whether anincreased level of resolution is required to satisfactorily identify alocation. Thus, in some embodiments in which a location must be veryaccurately identified, a higher level of resolution may be required andfurther subdivision may be required. In some embodiments, for example,the determination of whether further subdivision is required can bebased on information received from the user. In some embodiments, thisinformation can be received from the user at the time of input relatingto a location, or in connection with the creation of a user account. Insome embodiments, for example, the determination of whether furthersubdivision is required can be based on information stored in the userdatabase 414 in the memory 410. In some embodiments, this informationstored in the user database 414 can include, for example, informationrelating to the highest level of resolution that the user may access, orother similar information. In some embodiments, for example, thedetermination of whether further subdivision is required is based on thetype of feature whose location is being identified. Thus, in someembodiments, the central processing system 402 can include featuresconfigured to determine the size of the requested location such as thesize of a building whose location is being requested, the size of ageographic feature whose location is being requested, or any othersimilar information, and the resolution, and thus the determination ofwhether further subdivision is required, can be based in part on thesize of the feature for whom the location is being requested.

If further subdivision is required, then the process 520 returns toblock 522 and the division process is repeated. Returning again to block528, if further subdivision is not required, then the process 520proceeds to block 530 and the process 500 continues as described in FIG.5 .

FIG. 5B depicts another embodiment of a process 540 for performing thesteps of block 506 of FIG. 5 . Like the process 520 depicted in FIG. 5A,the process 540 depicted in FIG. 5B can be performed by the centralprocessing system 402. In some embodiments, and as depicted in FIG. 5B,the process 540 begins at block 542 and the central processing system402 determines a first dimension of an area. In some embodiments, thearea for which a first dimension is being determined is a parent areathat is to be divided into a plurality of child subareas.

In some embodiments, for example, information relating to the parentarea can be retrieved from the memory 410, and this information can beused to determine a first dimension, or, for example, this informationcan include a first dimension. In some embodiments, the first dimensioncan be, for example, the maximum dimension in a first direction of theparent area.

A variety of techniques can be used to determine a maximum dimension ina direction of the area. These can include, for example, collectingmeasurement data relating to the dimension of the area in a singledirection, and determining the largest value of the measurement data.

After a first dimension of the parent area is determined in block 542,the process 540 moves to block 544 and a second dimension of the area isdetermined. In some embodiments, the area for which a second dimensionis being determined is a parent area that is being divided into aplurality of child subareas, and can be, for example, the same parentarea for which a first dimension was determined.

In some embodiments, for example, information relating to the parentarea can be retrieved from the memory 410, and this information can beused to determine a second dimension, or, for example, this informationcan include a second dimension. In some embodiments, the seconddimension can be, for example, the maximum dimension in a seconddirection of the parent area.

After a second dimension of the parent area is determined, the process540 moves to block 546 and the parent area is divided into subareasbased on the first and second dimensions. In some embodiments, theparent area can be divided into child areas and/or child subareas basedon the first and second dimensions by determining a desired size of thesubareas. In some embodiments, for example, the first dimension of thearea can be divided by the desired size of the subareas to determine thenumber of divisions of the area to be made in the direction of the firstdimension. Similarly, in some embodiments in which the size of thesubareas is known, the value of the second dimension can be divided bythe desired size of the subareas to determine the number of divisions tobe made of the area in the direction of the second dimension.

Having determined the number of divisions to be made in the direction ofthe first dimension and in the direction of the second dimension, insome embodiments, for example, a group of first parallel lines and agroup of second parallel lines can be generated to divide the area intosubareas.

A variety of techniques can be used to divide the area into a number ofsubareas. Further these techniques are not limited to the abovedisclosures, but include, for example, any number of techniques capableof dividing an area into a number of subareas.

After the area is divided into a plurality of subareas based on thefirst and second dimensions, the process 540 moves to decision state 548and the central processing system 402 determines if further subdivisionis required. In some embodiments, the determination of whether furthersubdivision is require is based on whether an increased level ofresolution is required to satisfactorily identify a location. Thus, insome embodiments in which a location must be very accurately identified,a higher level of resolution may be required and further subdivision maybe required. In some embodiments, for example, the determination ofwhether further subdivision is required can be based on informationreceived from the user. In some embodiments, this information can bereceived from the user at the time of input relating to a location, orin connection with the creation of a user account. In some embodiments,for example, the determination of whether further subdivision isrequired can be based on information stored in the user database 414 inthe memory 410. In some embodiments, this information stored in the userdatabase 414 can include, for example, information relating to thehighest level of resolution that the user may access, or other similarinformation. In some embodiments, for example, the determination ofwhether further subdivision is required is based on the type of featurewhose location is being identified. Thus, in some embodiments, thecentral processing system 402 can include features configured todetermine the size of the requested location such as the size of abuilding whose location is being requested, the size of a geographicfeature whose location is being requested, or any other similarinformation, and the resolution, and thus the determination of whetherfurther subdivision is required, can be based in part on the size of thefeature for whom the location is being requested.

If further subdivision is required, then the process 540 returns toblock 542 and the division process is repeated. Returning again to block548, if further subdivision is not required, then the process 540proceeds to block 550 and the process 500 continues as described in FIG.5 .

Some embodiments relate to methods of providing location information. Insome such embodiments, the central processing system 402 can receive,for example, a request for location information and can, in response tothe request, provide location information. FIG. 6 depicts one embodimentof a process 600 for providing location information. As depicted in FIG.6 , the process 600 begins at block 602 and a request for locationinformation is received. In some embodiments, the request for locationinformation can be provided by a system user, and in some embodiments,the request for location information can be provided by a third party,such as, for example, by a webpage. In some embodiments, this locationinformation can correspond to a desired destination. In someembodiments, for example, the request for location information can bereceived by the central processing system 402 which can be a componentof, or separate from the user device 404. Thus, in some embodiments inwhich the central processing system 402 is a component of the userdevice 404, the request for location information can be received in theform of a user input into the user device 404. Additionally, in someembodiments in which the central processing system 402 is separate fromthe user device 404, the request for location information can bereceived from the user device 404. In some embodiments, for example, therequest for information is received at the communications module 418 ofthe central processing system 402.

After the request for location information is received at block 602, theprocess 600 moves to block 604 and a first signal componentcorresponding to and/or identifying a geographic area within a locationidentification grid is identified. A person of skill in the art willrecognize that a variety of techniques can be used to identify the firstsignal component and the present disclosure is not limited to anyspecific technique for identifying the first signal component.

After the first signal component is identified from the received requestfor location information, the process 600 proceeds to block 606 and asecond signal component corresponding to a subarea within the geographicarea is identified from the received request for location information.For example, the identified sub area may be a smaller region within thelarger area which includes the location identified in the receivedrequest. In some embodiments, for example, the signal can compriseindicators separating the first signal component from the second signalcomponent. In some embodiments, the first signal component and thesecond signal component can be identified by use of these indicatorswithin the signal.

After the second signal component corresponding to a subarea within thegeographic area is identified, the process proceeds to block 608 and therequested location is determined based on the first and second signalcomponents. In some embodiments, this determination can include, forexample, querying the memory 410 for information relating to apreexisting location identification grid 100 and comparing the first andsecond signal components to information stored in the memory 410relating to the pre-existing location identification grid 100.

In some embodiments, the determination of the requested location canfurther include, for example, the identification of the location of asecond location that can be, for example, the location of the userdevice 404. This second location can be identified by a user inputand/or can be made in connection with any feature, system, and/orcomponent capable of determining the location of the user device 404.Information relating to the second location can be provided to theprocessor 408 which can, in connection with the memory 410 determinedirections from the second location to the requested location. Thesedirections can comprise, for example, a heading, a distance, a routealong existing streets and/or paths, or any other desired form ofdirections. In some embodiments, the route along existing streets and/orpaths can be selected based on the shortest distance between therequested location and the second location, based on the estimated timeto move between the requested location and the second location, and/orany other parameter for route selection.

After the requested location is determined based on the first and secondsignal components, the process 600 moves to block 610 and locationinformation is provided. In some embodiments, for example, in which thecentral processing system 402 is separate from the user device, thelocation information is provided from the central processing system 402to the user device 404, and can be provided to the user device 404 via,for example, the communication system and network 406. In some in whichthe central processing system 402 is a component of the user device 404,the location information is provided from the user device 404 to theuser. Thus, in some embodiments in which a route is determined betweenthe requested location and the second location, the route can beprovided to the user device 404 and/or to the user.

The process 600 depicted in FIG. 6 can include more or fewer steps thanthose depicted in FIG. 6 , and the steps of process 600 depicted in FIG.6 can be performed in the same or in a different order. Further, thesteps of process 600 can include additional subprocesses and furthersteps.

FIG. 6A depicts one embodiment of a subprocess 620 performed as a partof a step depicted in FIG. 6 , and specifically as a subprocess of block608 from FIG. 6 . As depicted in FIG. 6A, the process 620 can be used todetermine the requested location based on the first and second signalcomponents.

The process 620 begins at block 622 and the first geographic areacorresponding to a first signal component received in the receivedrequest for location information is determined. In some embodiments, theprocessor 408 can compare information received from the memory 410 withthe first signal component. This comparison can be used to determine thefirst geographic area corresponding to the first signal component.

After the determination of the first geographic area corresponding tothe first signal component, the process 620 proceeds to block 624 and asecond geographic area corresponding to a portion of the second signalcomponent received in the received request for location information isdetermined. In some embodiments, for example, information received fromthe memory 410 can be compared with the second signal component todetermine the second geographic area corresponding to the second signalcomponent. For example, the second signal component can comprise a textstring identifying a second geographic area. Thus, the identificationfound in the text string of the second signal component can be used toidentify the second geographic area.

After the second geographic area corresponding to a portion of thesecond signal component has been determined, the process 620 moves todecision state 626 and the central processing system 402 determineswhether the from the received request for location informationidentifies additional areas. Referring to FIGS. 3A-3C, in someembodiments, a signal can include more information than identificationof just the first geographic area and the second geographic area. Insome embodiments, after the first geographic area corresponding to thefirst signal component has been determined and the second geographicarea corresponding to a portion of the second signal component has beendetermined, the process determines whether the signal includesinformation identifying further geographic areas.

If the central processing system 402 determines that the signalidentifies additional geographic areas, then the process 620 returns toblock 624 and determines further second geographic areas correspondingto a portion of the second signal component.

Returning again to block 626, if the central processing system 402determines that the signal does not identify additional areas then theprocess 620 moves to block 628 and proceeds to block 610 as depicted inFIG. 6 .
